Nicolas Pitre is a Senior Software Engineer based in Montreal with 26 years of deep expertise in Embedded Linux, ARM architecture optimizations, and fixed-point math. He has driven kernel and platform support across companies like BayLibre, Linaro (as an ARM Linux kernel expert in the Office of the CTO), Marvell, and MontaVista, consistently focusing on production-quality Linux for ARM targets. His open-source work includes substantive contributions to the widely used OpenOCD project—improving ARM simulation, Thumb-mode single-stepping, and adding semihosting support—and usability and performance improvements to the ncurses spreadsheet sc-im. Colleagues rely on him for low-level debugging, architecture-aware optimizations, and pragmatic design trade-offs between performance and maintainability. A polytechnic-trained engineer who began by enabling Linux on custom ARM routers and accessibility technology, he blends systems-level rigor with a long track record of shipping reliable embedded software.
